Subject: [PATCH 1/6] feat(wasm-solana): add SPL Stake Pool instruction
 decoding for Jito

Add support for decoding SPL Stake Pool instructions used by Jito
liquid staking. This enables WASM-based parsing of Jito staking
transactions for parity with BitGoJS.

Changes:
- Add spl-stake-pool dependency for official Borsh deserialization
- Add STAKE_POOL_PROGRAM_ID constant for SPoo1Ku8WFXoNDMHPsrGSTSG1Y47rzgn41SLUNakuHy
- Add StakePoolDepositSol and StakePoolWithdrawStake instruction types
- Add decode_stake_pool_instruction using official StakePoolInstruction enum
- Add TypeScript interfaces for stake pool instructions
- Add Jito transaction parsing tests using BitGoJS test fixtures

Ticket: BTC-2932

Subject: [PATCH 2/6] feat: add transaction building core infrastructure

Implements the core transaction building functionality using Solana SDK:

- types.rs: TransactionIntent, Nonce (blockhash/durable), Instruction variants
- build.rs: Transaction builder using solana-sdk 3.x types
- Uses SDK instruction builders: system_ix::transfer(), advance_nonce_account(), etc.
- Uses ComputeBudgetInstruction for priority fees

Supported instructions:
- Transfer, CreateAccount, NonceAdvance, NonceInitialize
- Allocate, Assign, Memo, ComputeBudget

Ticket: BTC-2955

Subject: [PATCH 3/6] feat(wasm-solana): add Stake Program transaction building

Add support for building native staking instructions:
- StakeInitialize: Initialize stake account with authorized staker/withdrawer
- StakeDelegate: Delegate stake to a validator
- StakeDeactivate: Deactivate a stake account
- StakeWithdraw: Withdraw from a stake account
- StakeAuthorize: Change stake account authorization

Ticket: BTC-2955

Subject: [PATCH 4/6] feat(wasm-solana): add SPL Token transaction building

Add support for building SPL Token instructions:
- TokenTransfer: Transfer tokens using TransferChecked for safety
- CreateAssociatedTokenAccount: Create ATAs with automatic address derivation
- CloseAssociatedTokenAccount: Close token accounts and reclaim rent

Supports both Token Program and Token-2022 via configurable program ID.

Ticket: BTC-2955

Subject: [PATCH 5/6] feat(wasm-solana): add Jito Stake Pool transaction
 building

Add transaction building support for SPL Stake Pool (Jito liquid staking):
- StakePoolDepositSol: deposit SOL into stake pool, receive pool tokens
- StakePoolWithdrawStake: withdraw stake by burning pool tokens

Uses spl-stake-pool crate with BorshSerialize for proper instruction
data encoding. Includes all required account metas for both operations.

Subject: [PATCH 6/6] feat(wasm-solana): add TypeScript tests and types for
 Stake, Token, and Jito

- Add TypeScript interfaces for all builder instruction types:
  - Stake Program: StakeInitialize, StakeDelegate, StakeDeactivate,
    StakeWithdraw, StakeAuthorize
  - SPL Token: TokenTransfer, CreateAssociatedTokenAccount,
    CloseAssociatedTokenAccount
  - Jito Stake Pool: StakePoolDepositSol, StakePoolWithdrawStake

- Update parser types to include decimalPlaces and programId for
  TokenTransferParams, and add StakeInitializeParams

- Add comprehensive TypeScript tests for all new instruction types:
  - Stake Program tests (initialize, delegate, deactivate, withdraw,
    full staking flow)
  - SPL Token tests (transfer, create ATA, close ATA, transfer with ATA)
  - Jito Stake Pool tests (deposit sol, withdraw stake, deposit with ATA)

All 73 tests passing.
